IMPROVEMENT IN REVOLVING STEAM-BOILERS.` t

Speeilirai -n forming part of Letters Patent No IMLGS', datei J.\nuary20, 1874; application tiled June 25, 1873.

Z'o all whom fit may concern:

Be it known that I, BENJAmN T. BAnBrr'r, otl the city, county, and Stateot New York, have invented an Improvement in Revolving Steamdoilers, otwhich the following is a specification This invention consists in arevolving tubu troduced through the one trunnion of the tubular body israpidly converted into steam by or as it enters the tapering radialtubes in their lower range of motion, and the steam thus produced passedott' through the opposite trunnion ot' the tubular body, the wholeforming a very eliicient steam-generator, capable ot' producing steam iilia-shes or from small. supplies of water with perfect safety, and withevery convenience as regards construction and repairs ot' the boilerwhen necessary.

ln. the accompanying drawings, Figures 1 and 2 represent sectionalelevations, in planes at right angles to each other, ot' a revolvingsteam-boiler constructed in accordance nigh my invention.

A is a horizontallyarranged tubular body or cylinder, provided withhollowr trunnions b L', which rest and turn in bearings c c ot' achamber or case, E, and pass through stuit'- ing-boxes d, also the oneot' which carries a gen-ring or pulley, c, for rotating the boiler. Saidease or chamber B contains the grate f,

ash-pit g, and draftoutlet or chimney h for the gaseous products ofcombustion. The hollow tubular body A is studded, preferably .in anirregular Iuanner, or out of line with each other as regards eachlongitudinal row or line, with hollow tapering radial tubes C, closed attheir outer ends, but in communication at their inner ends with saidbody A.

The water is introduced by a small stream or in jets through the hollowtrunnion b, and is rapidly converted into steam by or as it enters thetapering radial tubes C in their lower range. ot' motion, and the steamthus produced passed oft along the opposite trunnion b', the taperingshape of the radial tubes providing for the quick escape of the steam,and facilitating clearance ot' sediment or deposit as their verticalposition is reversed. The construction, too, by the separate insertionof the tubes C, facilitates transportation, and aftords much convenienceas regards putting together `or taking apart, and substitution, whenrequired, ot the details of the boiler, and the structure generallycombines `safety with economy and efficiency, together with freedon forindepend ent expansion and contraction of the parts.

Nhat is here claimed, and desired to be sc cured by Letters Patent, is-

The revolving tubular body A, studded with hollow tapering radial tubesC, and provided with hollow trunnions or bearings b I), substantially asspecified. A
